Elizabeth Levi noticed there was a spike in gun violence in 2010, and mapped the weapons used in each homicide for the years of 2010-2014. According CBS, police linked the spike in 2010 to the release of felons involved in the drug trade. Elizabeth found that incidents in Roxbury, Mattapan and Dorchester were more likely to include gun violence, while outer neighborhoods were more likely to be stabbings.

Maggie Quick analyzed the years 2012-2014 and mapped the weapons used in each homicide with their relation to Boston Public Schools. She found schools in East Boston were close to the the site of four different homicides from 2012–2014, whereas across the water in Charlestown there were no homicides in those years. Because Mattapan, Roxbury and Dorchester have higher rates of homicides in general, they had more incidents occur close to schools.
